(Cl. 160-90) The present invention relates windows.

Storm windows of the self string type generally cornto self storing storm prise a frame which carries upper and lower glazed sash it is necessary to rst remove the stored lower glazed.

sash, and then remove the upper glazed sash, in order to remove the screen. When the glazed sash is in the lower position and the screen is stored, it is necessary to remove the screen before the lower glazed sash can be removed. This makes it inconvenient to open the storm window. A further disadvantage of the multiple track storm window resides in its higher cost of manufacture as compared to the one track or trackless window.

It is an object of the present invention to provide a storm window in which the easy change over of the multi track storm window is embodied in a trackless one over one type of window, and in which the 'various sashes are more easily removed or opened. The one over one type window is the designation in the trade for the type in which the upper and lower glazed sashes are in alignment. v

Another object of the invention is to provide a trackless storm window in which, when the screen sash is positioned in the lower opening of the frame, the glazed sash may be quickly and easily shifted from its storage position to a position closing the screened opening by a sliding movement, without having to remove the screen, and wherein the glazed lower sash is secured in such position.

Another object is the provision of a one over one storm window in which the upper glazed sash is removably held in position independently of the other sashes.

Another object is the provision of a storm window having a screen sash arranged to hold a glazed sash securely in parallel relation to close the screened opening.

In accordance with the present invention I provide a trackless storm window frame of the one over one type in which the upper glazed sash is releasably retained by the'frame against dropping, and against moving inwardly, and in which the lower opening may receive the glazed sash or screened sash, as desired, in alignment with the upper glazed sash. When the screened sash is in the lower opening it is retained at the bottom by a liange dep pending into a groove in the bottom or sill of the window frame, and the top of the screened sash may be retained against inward movement by a spring or by a releasable interlock with the upper sash. In this position of the screened sash the lower glazed sash may be stored `in the upper portion of the frame parallel to and covering 2,857,963 l Patented Oct. 28, 1958 the upper sash, or it may be lowered by a sliding movement to the lower portion of the frame parallel to and covering the screened sash. The screened sash has-an inwardly extending ange provided with an upwardly opening groove, and the lower edge of the lower glazed sash has adepending flange received in said groove, when the glazed lower sash is lowered. The lower sash thus is releasably held at its bottom by the screened sash, which in turn is held by the frame, and at its top it is retained by a spring or the like. It will be seen that in this latter position storing of the screened sash Ais not necessary. To make the seasonal change it is only necessary to move the lower glazed sash to its stored position by an upward sliding movement. When the glazed sash is in stored position, the screened sash is easily removed by raising its depending ange out of the groove of the frame and drawing the sash inwardly, there being a pocket in the head of the frame deep enough to allow the upper sash to lift enough for the ange of the lower sash to raise out of the groove in the sill.

lf desired the screened sash may be removed from the lower opening, in which case, the lower glazed sash may be slid from its stored position to its operative position in alignment with the upper glazed sash. The screen then may be inserted into its stored position. In such arrangement the llange on the bottom of the lower glazed sash is received in the groove in the bottom of the frame, and the upper end of the lower glazed sash is retained by a spring or by releasable interlock with the bottom of the upper sash, or in any other manner desired. The glazedlower sash is easily removed by lifting the sash and pulling it inward. The screened sash may be stored in the upper position parallel to the upper sash if desired, and in such position it is preferred that the screened sash overlap the lower glazed sash.

The invention also comprises a novel dietent for holding the upper sash in raised position, this detent comprising an opening in the outer retaining ange of the storm window frame jamb and a struck out depending tongue on the bottom of the sash adapted to enter and overlie the opening.

The invention will be described in greater detail in con nection with the accompanying drawing illustrating a preferred embodiment of the invention by way of example,

Referring to the drawing, .the storm window frame comprises. left .andrightstiles `orjambs. 1, 1' which are of generally Zzshape in .cross section, and bottom and top railsV 2, 2 respectively, :the rails and Stiles being secured togetherin vany suitable manner, as b y self tapping sheet metal Ascrews or the like. Each stile ,comprises an outer inturned lla-nge 4, .a web :5, and a ange 6, and the storm window frame may be secured to the outer stop strip 7 of the conventional window frame, by screws or the like, passing throughr flange .6 into the frame.

Y The bottom rail .or sill 2.of the storm window frame may be formed .as fanextruded section and as shown in Figure `1.0, comprises vertical walls 8, 9 joined by a stepped vhorizontal Awall 31.0 from which extends a tongue 1.14 that provides an upward-opening ygroove 12. A rib or bead 13 yat .the lowerend vof wall :8..provides a reinforcement tov increase the rigidity .of the wall 8. A sealing strip 14 is ,provided to seal thelower .edge `of the rail, and bent over tabs 15 at the .ends ihold the strip. in position. The top rail-or head is Aof similarconstruction and therefore will notbeV described in detail, Ibut where necessary to refer to details ofthe top Yrail the .part will be .desig nated by a primed similar numeral. At the bottom the ends of .the bottom rail (Fig. 2) abut webs 5 of the stiles 1, .1 with the flanges 4. .overlapping the bottom rail, and

the stiles and `rail are :secured together by self tapping screws. At the top (Fig. 4) the horizontal wall 10 is grooved at 16 near :the .ends and the bead 13 is cutaway at the ends to .receive the-flanges .4, which are held against tongue 11 iby self tapping screws. Near the middle of each stile is secured a spring clip bracket 17, which may be riveted to flange A6. The `spring clip bracket provides tabs 17a, 1'7b .and 17e` ybetween which the bowed leaf spring 18 is received, the spring being loosely retained by means of punched teats received in similar punched sockets in the tabs.

The upper glazed sash 21 is received between the webs .of the left and =right stiles and is biased against anges 4 by `engagement by the upper end of spring 18. The anges 4 are each cut to provide an edge at 22 and the upper adjacent partfof flange v4 is cut `and bent out to' form-a `tab 23. The lower rail v2.4 (Figs. 7 and l2) of the upper sash has a depending yflange 25 the ends of which are offset at 26 to receive the end 22 of flange 4. The sash '21 may be raised into upper .rail 2 high enough to allow flange .25 Ato pass yover edge 22, and then by lowering the sash slightly `edge 22 is received in the offset 26 and engages the bottom lof the window `rail 24 ,to act as a stop. llnother words,each offset end 26 of ilange 25 is received in the kerf provided between the edge 22 and the tab 2 3 Iofthe, adjacent jamb flange 4. This holds the upper glazed sash lagainst .dropping or being pushed inwardly.

The screened sash-27 .(iFigs. 8 and 9) has a lower rail 28 Lfrorn which depends a ange 29 on its interior side. The screened sash is inserted into the frame substantially as illustrated in Figure l0 in connection with the lower sash, until Aits .upper railengages the upper glazed sash. and if necessary, the upper -sas'h may Ibe lifted by such engagement to .allow .insertion of :the screened sash Ainto the frame. After .being thus inserted the screenedvsash is .pulled down slightly* to cause its flange 29 to .enter groove 12 and thereby retain the sash at the bottom against inward displacement from .the frame. A flange 30extendi@ from the .lower .rail of the sash serves as a hand-lift. The bottom rail 24 (Fig. 13) of the top sash may have struck out tonguesl whichjlitinto the external groove 32 aroundthe screened sash, and this interlocking arrangement holds the'screened sash from being pushed inward atthe top. lt willbe noted that when the screened sash is in `the lower opening, the lower glazed sash 33 is in its upper stored position shown in Fig. 9 substantially parallel and covering the upper glazed sash 21. Although the upper leaf of the spring 18 pushing the two sashes 33 and 21 against flange 4 is enough to prevent the glazed Sash from dropping, 1 prefer to provide struck out tabs 34 on the lower end of the spring to provide a more positive lock to hold the stored lower `sash in position.

The lower glazed sash 33, as shown in Figures 8 and 9, has a depending ange 36 on its interior side and a horizontal ilange 37 is provided to serve as a hand lift. The flange 36 of the screened sash is formed to provide an upwardly opening groove 38 in registry with the flange 36. To lower the lower glazed sash from its stored position, the spring 18 is drawn to the left (Fig. 9) to disengage the tab 34 from the bottom of the sash, and the lower glazed sash 33 is slid downwardly until its flange 36 nests in the groove or socket 38 of the screened sash. in this position the lower end of spring 18 holds the upper ends of glazed sash 33 and screen sash 27 4against the flange 4, and at vthe bottom the screen sash is held in position by its flange -29 nesting into groove 12, while the lower glazed sash has its ilange 36 nesting into groove 3.8.

1f desired, the window Amay be left in the position shown in Figure 8 throughout the winter season as this provides a glazed upper and `lower sash closing the openings of the frame. To convert the window from this condition to a screened window, it is necessary only to slide the lower glazed sash 433 .upwardly to stored position where it is retained by spring 1S `as yshown in Figure 9, thus uncover.- ing the screened sash. However, if it is not desired to have the screened sash in yits lower position throughout the winter, the screenedsash can be removed and `placed in stored position as shown in Figures 10 and 1l, and the lower sash 33 then inserted in the frame with its lower flange 36 received in the groove 12-of the lower rail of the frame. lIn .this lposition the tab 31 in the upper sash extends into a socket 39 formed in the upper rail 41 of the lower sash so .astio provide an interlock holding the upper end .of the Vlower sash against displacement. However, if this interlock is omitted, the lower sash will still be held `against displacement by the overlap of the yscreen sash, which in .turn can move away from flange 4 only a short distance before it encounters the spring clip 17. In the positionshown in Fig. ll it is easy to remove the lower glazed sash, and this can be done without disturbing the sto-red screened sash 27 in any way. To remove the lower glazed sash 33 it is raised slightly until its flange 36 is lifted out `of groove 12, and then the sash is drawn backwardly as illustrated :in Figure 10 ito remove it. The lower glazed sash maybe restored `to its position merely by inserting its .upper .end Iirst into engagement -with the upper sashk 21, lifting sufficiently to enable the flange 36 to clear tongue 11, then pushing down the sash to cause its flange 36 to enter groove 12.

From the foregoing description it will be seen thatthe window structure .embodies the following advantages:

A. A lower construction cost by reason of the elimination of vertical tracks.

B. Easy interchangeability of screened and glazed lower sash.

C. For winter use, screen may ,be left in `lower opening, in which case Vthe window is converted to summer Iuse merely by sliding upwardly the lower glazed sash.

D. In summer position, screen is veasily removed without having `to remove lower sash.

E. 1n winter condition with the screen stored in the upper portion the window can be opened without disturbing the screened sash.

F. At all times all sashes are retained against removal from the exterior.
